To all whom it may concern:

Be itknown that I BENJAMIN C. Cas- SADY, a cit iz en/o-f the nited States, residing at Portland, in the county of Multnohave invented certain new and useful Improvements in Scissors; and I do herpby declare the following to be a full, clear, and exact description of the invention, such as will enable others.

skilled in the art to which it appertains to make and use the same.

' This invention relates to improvements in SCISSOIS.

The principal objectof the invention is to provide a pair of scissors which combine.

the features of the ordinary scissors and of the buttonhole scissors.

Another object is to. provide a pair of scissors, the portions of which are adapted to be separated and one of them reversed, to accomplish the above-named result.

Other objects and advantages will parent from the following description when taken in connection with the accompanying ing drawing,

drawing. I

In the drawing: Figure 1 is a plan view of a pair of scissors made in accordance with my invention, the same being in position of the ordinary shears, Fig. 2 is a plan view showing one of the blades reversed, thus converting the scissors into buttonhole scissors, Fig. Fig. 1, and Fig. 4 is a perspective view of the pivotal joint of the blades of the scissors.

Referring particularly to the accompany- 10 and '11 represent respectively a pair of scissors blades provided respectively with the finger hole handle portions 12 and 13. Intermediate the blade 11 and handle 12 ofithe scissors there is formed the vertical stud 14: having a transversely extending Thead 15 on the upper end. In the corresponding portion between the blade 10 and handle 12 of the other member there is formed'a circular opening 16 centrally within which are the oppositely disposed- "approximately semi-circular flanges 17 extending inwardly toward each other in spaced relation and each formed with a 'acurved recess 18 in the edge adjacent the iother flange. The space between the flanges receives the key head 15 while the recesses .8' receive the stud 14 and permit the mem- '\ers of the scissors to be rotated whereby tween the flanges 3 1s a section on the line 3-3 of freely move therethrough and permit the the head 15 will lie on top of the flanges and thus prevent the members from coming apart while at the same time permitting free pivotal movement therebetween.

Rigidly secured to the handle 13 is one end of a leaf spring 19, the other end of vby the handle 13 and extending in a direction toward the other handle 12 is a threaded stud 21 on which is mounted a threaded sleeve 22, this sleeve being adapted to be adjusted on the stud so as to limit the closing movement of the handles.

On the back of the blade 10 is an extension 23, disposed'intermediate the ends of the blade and having its outer edge beveled to provide a shear blade as indicatedat 24.

By .opening the scissors to a comparatively wide position, the head'15 will be brought into registry with the space be- 17 whereby the head will 'outer end, the result being that thecutting edge inclines downwardly and outwardly toward the point of the blade 10. This produces a perfect shearing action with the edge of the blade 11, and by adjusting 'the sleeve 22, the proportion of the edge 24 which willengage with the blade 11 for cutting action can be increased or decreased thereby regulating the length of the cut ofthe blade 23 and consequently the length of the'buttonholer Particular attention is called to the fact that the blade 10 carries the ordinary scissors blade edge on one side and on the other side the short inclined cutting blade ,10 means for 'detachably pivoting the members together whereby the said shear blade can be reversed to bring either of its cutting edges into cooperative engagement with the other blade.

In testimony whereo f, affix my signa- 15 ture, in the presence of two Witnesses. 1
